Recalling pre-stored 

/LENGTH data 

There are up to 20 pre-stored Resistance per unit values stored into memory. These values can be 
recalled and used for cable length measurement. 

1. 

In SETUP mode, press the 

RECALL

 button to recall pre-stored data.  

2. Press 

the 

SELECT

 button until the resistance per unit values appear. 

3. Press 

the 

RECAL

L button to step through the stored values. 

4. 

Turn the rotary switch to the proper range and press 

START

 to measure the cable length. 

NOTE: 

The range of length is 0.0001 ft or m to 9999K ft or m. 
When the cable is disconnected, OL 

 is displayed instead of OL FT or m.  

When the resistance is 0, 0 

 is shown instead of 0 FT or m. 

If the length is less than 0.0001 feet or meters but greater than 0, 0.0001 feet or meters is shown. 

 

Memory Record, Read and Clear 

Record 

1. 

With a reading in the display, press the 

REC / READ

 button. 

2. 

The memory location number will flash on the display and the data will be stored to that 
location. 

Read 

1. 

Turn the rotary switch to SETUP. 

2. Press 

the 

REC / READ

 button. The memory will flash and then the data in that location will 

be displayed. 

3. Press 

the 

▲▼

 buttons to scroll through stored data. 

Clear 

1. 

Turn the meter off. 

2. 

Press and Hold the 

REC / READ

 button and simultaneously turn the meter on. 

NOTE: 

The memory capacity is 3000 data records.  When 3000 records are exceeded, there will be a long 
beeping sound and no further data can be recorded..
